Yes, it could be flow limitation or apnea events waking you up abruptly; if it is, we should be able to see it in your charts at the relevant time.
A neurochemical issue may correct itself with time. It may be exacerbated by anxiety and stress, so take a look at that part of your life. And as always, you may want to talk with your doctor about the problem to see whether there are any medications that might help.
Unpleasant as they are, if these episodes don't last very long, you may just want to bear with them, knowing you will fall asleep for real in due course.

Another possibility is that there's a glitch occurring during the complex neurochemical hand-off from your waking controls of breathing to your sleeping controls.
It's good that PAP is helping some with this problem, and perhaps with time it'll fade away. In the meantime, when you experience this during the night, could you check the time and then the next day post a zoomed-in view of the period when you were having the jerks? Maybe a ten-minute zoom.
Attached is pre awakening and also attached is showing flow morphology when i feel i slightly restless due to disturbed breathing?
Let me know your thoughts.
Thanks so much for interpreting this. Its like you can see the reduction in air-flow in the longer minute view?
The arousal has me scratching my head. It seems to occur with that breath at around 1:32:30. You inhale, hold your breath, then take a sharp additional inhalation and again hold your breath. After that you're clearly waking up. Are there any flow limitations, snores, or leaks right around then? Is your respiration rate elevated in this stretch of the night? (That might indicate REM sleep.) There may just be no way to tell from the OSCAR data what precipitates this.
The tossing/turning graph: right after 4:16:30 you seem to have a little flow limitation followed by arousal or semi-arousal that includes a brief breath-holding. Maybe you were turning over at that point; we often hold our breath when we're exerting ourselves. After that, you have a short interval of deeper/shallower breathing that includes the CA. This is a bit of "periodic breathing." It probably indicates that the deeper breathing is washing out enough CO2 to reduce your drive to breathe, then the shallower breathing results in a bit of recovery breathing, which again washes out some CO2.... This is nothing to worry about in itself -- what's not so great is that you are tossing/turning and not getting restful sleep.

Thanks so much for your replies, I appreciate your knowledge.. I'll report back with some fresh graphs and also include the other data mentioned.
The tossing and turning - I was cleared of PLMD but my question is can tossing and turning at night also be potentially indicative of RLS? My sleep seems to be so yo-yo lately its hard to pinpoint whats causing at minimum the "light" sleep or "disrupted" sleep which is causing me to toss and turn.. Im even looking at getting my bowels checked as i can get quite gassy at night and wonder if the abdominal discomfort triggers the tossing and turning aswell?
A few things to consider.
Thanks again.
